如何对 Lucene.net 搜索中提供的所有单词执行模糊搜索
我正在尝试自学 Lucene.Net 在我的网站上实现。我知道如何做几乎所有我需要做的事情，除了一个问题。我试图弄清楚如何允许对搜索字符串中的所有搜索词进行模糊搜索。
例如，如果我有一个包含字符串 The big red Fox 的文档，我会尝试使用 bag fix 来匹配它。
问题是，似乎为了执行模糊搜索，我必须将 ~ 添加到用户输入的每个搜索词中。我不确定解决这个问题的最佳方法。现在我正在尝试这样做，
string queryString = "bag rad";
queryString = queryString.Replace("~", string.Empty).Replace(" ", "~ ") + "~";
第一次替换是由于 Lucene.Net 抛出异常，如果搜索字符串已经有 ~ ，显然它无法处理 ~~用一句话来说。这种方法有效，但如果我开始添加模糊权重值，它似乎会变得混乱。
有没有更好的方法来默认所有单词以允许模糊性？
I am trying to teach myself Lucene.Net to implement on my site. I understand how to do almost everything I need except for one issue. I am trying to figure out how to allow a fuzzy search for all search terms in a search string.
So for example if I have a document with the string The big red fox, I am trying to get bag fix to match it.
The problem is, it seems like in order to perform fuzzy searches, I have to add ~ to every search term the user enters. I am unsure of the best way to go about this. Right now I am attempting this by
string queryString = "bag rad";
queryString = queryString.Replace("~", string.Empty).Replace(" ", "~ ") + "~";
The first replace is due to Lucene.Net throwing an exception if the search string has a ~ already, apparently it can't handle ~~ in a phrase. This method works, but it seems like it will get messy if I start adding fuzzy weight values.
Is there a better way to default all words to allow for fuzzyness?
